INDIANA, 'ASSIGNOR T GENERAL CABLE 00E Y., A CORPORATION 0E NEW JERSEY wmnnve MACHINE Application filed .April 25,

This invention relates to coil winding machines of the multiple coil type wherein a plurality of separate coils of wireare wound on a core and the paper insertions between the Wire layers are formed by winding a, sheet of paper .about the entire stick; of coils after each layer is wound. In ma-- chines of this type, a gang of knives is arranged for movement toward and from the spindle for cutting the paper insertions be-- tween the separate coils. 'A cutter guard is usually provided for shielding the knives when in non-cutting position to prevent posbut as heretofore constructed, such guards have not been 'entirely adequate.

An object of this invention is to provide an improved cutter guard for machines of the ted and arranged to provide an operator with protection against accidental injury.

A further objec is to provide a cutter guard for coil winding machines'having an 6 improved construction arranged to be held 2 against displacement when the cutters are inoperative.

These and other objects parent to those skilled in this particular art are accomplished by means of the invention illustrated in the accompanying drawings in which, Q

Fig. 1 is a perspective view of'part of a coil winding machine provided with a cutter which will be apguard constructed and arranged in accordance with one embodiment of'this invention. Fig. 2 is a transverse sectional view through the machine shown in Fig. 1 illustrating one position of the parts, and j 4 Fig. 8 is a similar view showing in a difierent position.

. The illustrated embodiment of the present invention includes a frame which is associated with the gang of knives so as to cover the knife blades when the latter are in non-cutting position and to be moved to uncover the blades when they are shifted toward the winding spindle to cut the sheet material between the different coils. Means is provided for holding the guard against displacement the 4 parts 1931. Serial No. 532,760;

when the, cutters guard in cutter covering positlon.

The invention'is illustrated in. connection with a winding machine having the'usual' coil winding spindle 5 which may be driven by a suitablemotor 6 for winding a plurality.

of separate 00113 7 of wire 8 delivered'tothe machine from the usual supply spools (notv shown). After each layer of wire is wound; an insulating layer of suitable sheet material 9 received from a roll 10 is fed to the spindle: 5 and wound thereon, the single sheet being of sufficient width to extend the entire length of the stick of coils being wound'on the machine. The sheetmaterial is severed between the separate coils by a gang of knives which are movable into and out of cutting posi'-- tion. blade holders 11 provided with cutting blades 12 and secured to a cutter supporting shaft 13 mounted in supporting arms 14 which are pivotally secured to spaced upright frame members 15 of the machine. One of the cutter supporting arms is provided with an operating handle 16 by means of whichthe cutters are swung toward and from the spindle-into and out of sheet cutting position.

In order to coverthe blades 12 when .in non-cutting position so as to protect the operator against accidental injury,- av U- shaped cutter guard 17'is pivotally mounted on the cutter rod 13for swinging movement thereon and one arm 17 of the guard is eX-' tended above the supporting rod and connect-- ed by a link 18 to a curved guard actuator 1-9 having an arcuate slot 20 receiving supporting bolts 21 by means ofwhich the actuator is movably supported upon the adjacent arm 14. The lower.angularly.extending leg 2 2 of the actuator 19 engages the face of one of the uprights .15.- A spring 28 connects the upper portion of the extended guard arm 17 with the upper part of the actuator 19. The cutters and associated parts are normally held in non-cutting position by a weight 24 mounted on supporting arm'25'pivotally secured t o an ear 26 on the top face of the operating arm 14.

During normal operationof the winding 23 hold the machine, the weight 24 and spring are inoperative and the The knives include aplurality of.

sition shown in Fig.

parts in non-cutting position illustrated in Fig. 2, and it will be apparent that the guard 17 is held against accidental movement on the part of the operator, by the acuator 19 which obviously prevent movement of the guard 17, the angular position of the link 18 with relation to the arcuateslot 20 and hinge 21 being such that swinging movement of the guard 17 on the supporting rod 13 is resisted. WVhen it is desired to severe the sheet material between the coils, the cutters 12 are moved downwardly into cutting position, as shown in full lines in Fig. 3, by downward movement of the handle 16, which causes the cutter supporting arms 14 to swing downwardly around the supporting pivots, the supporting pins 21 moving through the arcuate slot in the guard actuator 19 to the position shown, the actuator being held against swinging movement byengagement of the leg 22 with the front face of the frame member 15, the actuator merely sliding downwardly along such face. The relative movement of the actuator and the arm 14 thus causes the link 18 to swing the guard 17 and uncover the blades 12 so that they can be moved into cutting engagement with the sheet material. Upon completion of the cutting operation, the arms 14 are returned to the po- I 2, the actuator 19 rides upwardly along the face of the frame mem ber 15 and the spring 23 which has been tensioned by movement into the cutting position shown in Fig. 3, holds the actuator 19 in operative position and causes the guard 17 to return to the position illustrated in Fig. 2.

The cutters and associated parts can be raised into the extreme upper position to give the operator access to the spindle 5 by lifting the handle 16 and moving the parts into the position shown in dotted lines in Fig. 3. In this position also the leg 22 of the cutter 19 remains in engagement with the frame me ber 15 and continues to maintain the guard 17 in protecting position over the blades 12.

Although I have described a specific embodiment of this invention in detail, it will e apparent that various changes and modifications can be made therein without depart ing from the spirit of the invention or the scope of the appended claims.
